A small practice goal
Choose one rule to keep in mind for this round. Apply it consistently rather than guessing what another version might allow. Refer to the controls when needed.
The purpose of your moves
Create one connected sea around numbered islands of exactly the stated size, without a 2×2 sea block. Read that aim before choosing your first action. Notice how the game responds to your input.
How a round unfolds
- Shade sea squares and leave islands white.
- Every island contains exactly one clue.
- Different islands cannot meet along an edge.
- Check puzzle verifies sizes, connectivity and forbidden sea blocks.
The controls to know
Click or tap squares or graph edges. Number boards include a digit pad. Undo reverses the previous change; Check puzzle validates the solution. Read a button’s label before selecting it. Use one clear input at a time.
See the idea in action
An island labelled 1 is already complete, so its edge neighbours must be sea. Your next round may have a different position, so inspect it before acting. Consider the next action carefully.
Notice this detail
Two numbered islands may not merge into one. Compare the situation with the worked example. Choose one rule to keep in mind for this round. Apply it consistently rather than guessing what another version might allow.
